The chapter opens with Tosano explaining that the radiation from the "splintering cell" is a signal sent by the brain to the rest of the body. When the signal is received, the brain interprets it as a signal from the outside world, but when it is received by the body, it is the signal sent from the inside world. This is why the brain is able to sense the signal. The chapter ends with the chapter's title sequence.
